https://bugzilla.suse.com/show_bug.cgi?id=1205740 Bug ID: 1205740 Summary: btrfs fails to act on fs if the fs is read-only Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: william.brown@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Transactional server mounts in read only mode on /. This causes all btrfs management commands to fail. # btrfs balance start -f -sconvert=dup -mconvert=dup -dconvert=single / ERROR: error during balancing '/': Read-only file system There may be more info in syslog - try dmesg | tail However if you (on the same filesystem/pool) do this to /home, it works since that's mounted rw. This is an extremely surprising and unintuitive behaviour. -- You are receiving this mail because: You are on the CC list for the bug.
